Abstract

L'invention concerne un système ambiophonique destiné à être utilisé avec un véhicule de loisir (RV) ayant un téléviseur ayant un écran de TV exposé sur un côté d'un corps du RV; un ou plusieurs haut-parleurs agencés pour émettre un son situé au niveau ou à proximité du téléviseur, et un ou plusieurs haut-parleurs montés sur un ensemble auvent rétractable. La pluralité de haut-parleurs peut être agencée pour produire un son enveloppant avec des haut-parleurs avant et des haut-parleurs arrière. Le système de son d'ambiance est conçu pour être utilisé pour générer un son d'ambiance à l'extérieur d'un corps du RV.
